Dice, coins and weather follow fixed rules we can’t track, but quantum events are different, and whether they are random at the deepest level is still argued.
Mind & MortalityAnswer
Is free will real, or does the brain decide before we do?
A famous experiment seemed to show that the brain makes our choices before we know it, so here is what it really found, what later work showed, and what is still open.
